Abstract
A different pathophysiological mechanism is widely accepted for gastric and duodenal ulcer. In particular, the exact role of gastrin in the determinism of nonhormone-dependent peptic ulcer disease has been completely clarified. The aim of the present study was to analyse fasting and postprandial serum gastrin levels in 99 duodenal ulcer patients, 17 gastric ulcer patients and 11 subjects presenting an association of gastric and duodenal ulcer. The possible correlation between postprandial gastrin concentrations and basal and maximal acid output in the 3 groups of patients has also been investigated. Fasting serum gastrin levels do not appear different among the 3 classes of patients, while postprandial gastrin concentrations are statistically higher at 15 minutes in duodenal ulcer patients and in subjects with the association of gastric and duodenal ulcer as compared to gastric ulcer patients. Mean fasting and stimulated gastrin levels are higher in gastric ulcer females than in males during the entire test and with a statistically significant difference at 30 minutes. The concentrations of the hormone are not different in males of the 3 groups of patients at basal time, while they are statistically lower at 15 and 30 minutes in gastric ulcer males compared to those with duodenal ulcer and the association of the localization. Finally, positive correlation has been observed between B.A.O. and M.A.O. and postprandial gastrin concentration in the 3 groups of patients, while there is an inverse correlation between the previous parameters as regards sex, both in gastric and duodenal ulcer.

Abstract
Gastric juice and urine samples from consecutive patients who underwent endoscopy for upper GI tract complaints were examined for the presence of mutagens. Patients endoscopically and histologically diagnosed as having either chronic atrophic gastritis (CAG) or gastric cancer (GC) had higher than normal levels of mutagens in their gastric juice and urine. The gastric juice pH of these patients was also elevated and, in the case of the CAG patients, contained detectable levels of nitrites. No correlation was however found between gastric mutagen levels and urinary mutagen excretion in the individuals examined.

Abstract
A simple routine endoscopic screening test has been sought for the diagnosis of chronic atrophic gastritis. An endoscopic-bioptic study was therefore carried out on 850 subjects presenting consecutively at a Digestive Endoscopy Department with dyspeptic-pain symptomatology. In a first sample of 389 patients, 2 biopsies of the gastric body and 2 of the gastric antrum were carried out, independently of the endoscopically documented macroscopic picture. Atrophic changes were in this way encountered in 65 patients (16.7%). In a second group of 461 patients, intragastric pH was determined extemporaneously during endoscopy. pH was = or greater than the chosen threshold value (3.5) in 117 patients and less than this value in 344. In all subjects with pH greater than 3.5 and, by comparison, in 130 with pH less than 3.5 biopsy was carried out on the gastric mucosa, 2 biopsies of the body and 2 of the antrum. Using this approach it was possible to determine the presence of atrophic changes in the gastric mucosa in 57 of 117 (48%) and in 25 of 130 (20%) respectively. In total, chronic atrophic gastritis was diagnosed in 83 of 461 subjects (18%). This percentage is comparable to that observed in the frequency of chronic atrophic gastritis using the more demanding and less selective test of bioptic sampling indiscriminately for all patient. So, the straight-forward determination of intragastric pH in a sample of gastric juice taken during digestive endoscopy would appear to meet the criteria demanded for a screening test and its wider use is recommended in routine endoscopic practice.

Abstract
The effect of chronic ethanol consumption on enzyme systems directly involved in carcinogen activation and detoxification were studied in rat upper alimentary tract tissue. Microsomal cytochrome P-450 (P-450) levels and glutathione levels as well as glutathione transferase and UDP-glucuronic acid transferase (UDPGT) activities were measured in mucosa scraped from esophagus, forestomach and glandular stomach of rats which had been pair-fed ethanol or dextrimaltose-containing diets. Esophageal and forestomach P-450 levels were increased in the ethanol-fed rats. The ethanol diet also produced a small but significant increase in esophageal glutathione transferase levels. Glutathione levels and UDPGT activity were unaffected. Since P-450 is directly involved in the activation of many chemical carcinogens, these results are consistent with the hypothesis that the increase in upper alimentary tract cancer risk associated with alcohol abuse is due, at least in part, to ethanol's altering the balance between carcinogen activation and detoxification.

Abstract
Gastric juice CA 19-9 levels were determined in 23 patients affected by gastric cancer, in 57 patients affected by chronic atrophic gastritis of different severities and in 55 'healthy' controls, undergoing endoscopy for upper gastrointestinal tract symptoms. Increased CA 19-9 levels were documented in chronic atrophic gastritis patients as well as in gastric cancer patients, the difference with respect to controls being statistically significant. However, there was considerable overlap between different groups. In particular, gastric cancer patients had CA 19-9 levels similar to those detected in moderate and severe chronic atrophic gastritis. CA 19-9 correlated with gastric juice pH and CEA concentration. Its values were not influenced by the patients' age or sex. In our opinion CA 19-9 gastric juice determination, although not useful in singling out patients harboring gastric neoplasia, may be used in identifying patients 'at risk' for gastric cancer and who might then be referred for more accurate investigations.

Abstract
138 consecutive patients with endoscopically and histologically confirmed benign gastric ulcer were investigated in order to evaluate the relationship between aging and parameters relating to gastric ulcer pathophysiology and natural history: prevalence in dyspeptic patients referred to an endoscopic unit, recurrences, gastric acid secretory capacity, peptic activity, incidence of precancerous and neoplastic changes. On the basis of our results, different populations of gastric ulcer patients seem to be identifiable: (1) young patients (aged under 40), with low prevalence and recurrence rates, with acid capacity above normal range, high peptic activity and no risk for precancerous or neoplastic changes, (2) middleaged subjects (41-50), with high prevalence and recurrence rates, high peptic activity and acid activity within the normal range, atrophic gastritis, intestinal metaplasia, dysplasia and low incidence of cancer, and (3) elderly patients (aged over 50), with lower prevalence and recurrence rates, frequent association with chronic atrophic gastritis, impaired acid and peptic secretion, in whom one may observe either an association of the ulceration with cancer or evolution of dysplasia into neoplasia. These observations confirm that elderly and middle-aged gastric ulcer patients should undergo routine follow-up, and that pathophysiological data should be taken into account before deciding upon antiulcer therapy.

Abstract
One hundred and forty-four patients with apparently benign gastric ulcer were endoscopically followed up in order to evaluate the outcome of the lesion. Particular attention was given to: (a) detect possible delay in diagnosing gastric cancer; (b) ascertain the frequency of association with epithelial dysplasia; (c) establish the role of markers, such as serum pepsinogen group I (PGI), and gastric juice CEA in predicting gastric ulcer evolution. Endoscopic and bioptic check-ups were carried out during the first year at 3, 6 and 12 months after endoscopic healing of the ulcer, and then at every symptomatic recurrence. Ten patients (6.9%) were found to present histological evidence of malignancy (within 3 months in six cases, between 6 and 12 months in three cases, and after 41 months in the rest). Four cases were early gastric cancers, and six had shown dysplastic changes of the mucosa at the edge or scar of the ulcer. Serum PGI levels were not significantly different in gastric cancer patients, while gastric juice CEA levels were sharply increased compared to those of gastric ulcer patients: nine out of ten patients had values above normal range. These data suggest that: (a) there may be some delay in diagnosing gastric carcinoma, and gastric ulcer patients should be controlled routinely more than once; (b) the presence of dysplasia indicates the need for prolonged follow-up, because of the high risk of association with or evolution into gastric cancer, and because of the higher number of early gastric cancer detections that this protocol allows; (c) further support in monitoring patients "at risk" may be afforded by gastric juice CEA determination.

Abstract
The endoscopic diagnosis of chronic atrophic gastritis is often underestimated, and most of the procedures adopted to increase diagnostic accuracy are time consuming and complex. In this study, we evaluated the usefulness of the determination of gastric juice pH by means of litmus paper. Values obtained by this method correlate well with gastric acid secretory capacity as measured by gastric acid analysis (r = -0.64, p less than 0.001) and are not affected by the presence of bile. Gastric juice pH determination increases sensitivity and other diagnostic parameters such as performance index (Youden J test), positive predictive value, and post-test probability difference by 50%. Furthermore, the negative predictive value is very high, the probability of missing a patient with chronic atrophic gastritis with this simple method being 2% for fundic and 15% for antral atrophic change. We conclude that gastric juice pH determination, which substantially increases diagnostic accuracy and is very simple to perform, should be routinely adopted.

Abstract
The aim of the study was to identify the clinical markers useful in characterising slow healing and relapsing gastric ulcer patients. Ninety nine subjects entered the short term and 79 the long term study (12 months). The following parameters were taken into account: therapy, sex, age, smoking habit, alcohol consumption, analgesic intake, peptic ulcer family history and onset of the disease. Results of the studies were analysed by means of chi 2 test and logistic regression, both in stepwise and in specifying models. Cigarette smoking was found to be the most important risk factor of non-healing (p = 0.04). In women with late onset of the disease, cigarette smoking identified the gastric ulcer subjects at higher risk of non-healing with a predictive probability of 0.4679. Age under 50 years was found to be the most important risk factor of relapsing throughout the entire 12 month follow up period (p = 0.025). In those under 50 years, cigarette smoking and negative peptic ulcer family history in combination, identified the gastric ulcer subjects at higher risk of relapsing, the predicted probability being 0.6027. It is concluded that cigarette smoking is the most important risk factor for non-healing and those who relapse under the age of 50. The possibility of singling out categories of patients more prone not to heal and to relapse suggests new strategies in the management of gastric ulcer disease.

Abstract
The aim of the present work was to study gastric acid secretion in control subjects and in gastric and duodenal ulcer patients and to evaluate sex, age, body weight, blood group, cigarette smoking and the intake of H2-blockers in the 24 hours preceding gastric acid analysis. The results obtained seem to indicate that 6 micrograms/kg b.w./i.m. Pentagastrin is the best stimulus and that basal secretion may be assessed in thirty minutes, without altering the BAO value. Factors such as cigarette-smoking and H2-blockers intake on the one hand and body weight and male sex on the other influence gastric juice output and should therefore be considered in interpreting the results.

Abstract
This article presents a review and update of recent experiments conducted in collaboration with Dr. C. S. Lieber on mechanisms underlying the increased cancer risk associated with alcohol abuse. Ethanol has been found to be a potent inducer of microsomal enzymes involved in carcinogen metabolism in a variety of rat tissues including liver, esophagus, lungs, and intestines. In some of these tissues, ethanol's inductive effect on microsomal cytochrome P-450 enzyme activity may result in enhanced levels of electrophilic metabolites of procarcinogens which are not readily detoxified. In addition, chronic ethanol feeding has been found to depress the activity of O6-methylguanine transferase, an enzyme involved in the repair of carcinogen-induced DNA alkylation. The effects of ethanol on carcinogen metabolism and on DNA repair would be expected to enhance the initiation phase of chemically induced cancers.

Abstract
Tissues derived from male Sprague-Dawley rats which had been pair-fed isocaloric ethanol or carbohydrate control diets for 4 weeks were used to determine the effect of chronic ethanol exposure on the activation of the smoking and diet-associated procarcinogen nitrosopyrrolidine (NPY). Microsomal preparations from lungs and liver and S9 fractions from alimentary tract mucosa were tested for their capacity to activate NPY to a mutagen by the Ames Salmonella assay. Chronic ethanol exposure resulted in an increased capacity to activate NPY by microsomes derived from liver, lungs, and esophagus but not from stomach. The three tissues in which enhanced activation of NPY was observed in the present study also have been noted in epidemiological studies to be target sites of alcohol abuse-associated increased cancer risk. The results presented here suggest that dietary ethanol's effect on carcinogen metabolism may be responsible, at least in part, for the increased cancer risk observed in chronic alcohol abusers.

Abstract
There have been recent findings of gastric cancer in patients treated with cimetidine but too soon after treatment for that drug to have had a pathogenetic role. Ranitidine has been shown to induce slight changes in the gastric mucosa. In 117 patients with gastric ulcer followed-up in some cases for 24 months, five cases of cancer were detected, one after more than a year of follow-up. The numbers were too small to allow any conclusion to be drawn regarding relationships with medication. No significant differences in incidence of gastric epithelial dysplasia between control patients and patients treated with cimetidine or ranitidine were found. No dysplastic lesions were seen during a brief follow-up of 19 duodenal ulcer patients and a few gastric ulcer patients treated with pirenzepine but the data is too limited to allow conclusions to be drawn.

Abstract
In order to ascertain the role of gastric carcinoembryonic antigen (CEA) determination in detecting patients with a risk for gastric cancer, 69 subjects were studied; 23 were referred for endoscopy because of dyspepsia but without obvious macroscopic lesions, 27 with duodenal ulcer, 11 with benign gastric ulcer, 8 with gastric cancer. The following results were obtained by subdividing the material according to the histologic interpretation of the results of gastric mucosal biopsies: (1) in the presence of minor histologic abnormalities of the gastric mucosa, CEA in gastric juice was under 100 ng/ml in all but five cases; and (2) in moderate or severe chronic atrophic gastritis (associated or otherwise with intestinal metaplasia or dysplasia), and in gastric cancer, gastric CEA ranged between 224 and 3120 ng/ml in all but two cases. Although not diagnostic for gastric cancer, gastric CEA is a promising test in detecting patients at risk, including those with dysplasia of the gastric mucosa.

Abstract
The appearance and clinical significance of an atypical fraction of serum alkaline phosphatase called "biliary" have been evaluated in patients with primary liver cancer (PLC) and control subjects. The "biliary" fraction was present in all 42 PLC patients and proved to be the most sensitive of the biochemical parameters utilized. The association with alpha-fetoprotein determination allowed us to identify patients affected by hepatic pathology of neoplastic type, with a diagnostic efficiency of 92%.

Abstract
We evaluated the changes over 1-55 months in mild gastric epithelial dysplasia (a relatively frequent, but not widely studied histological lesion) in 20 patients (11 with benign gastric ulcer, eight with chronic gastritis, and one after Billroth 2 operation), in order to ascertain whether to follow-up such patients in the future. Regression of the lesion was documented in 13 (65%), and no change in six (30%). Progression from mild to moderate dysplasia occurred in only one patient (5%). As mild dysplasia regresses or remains unchanged in most patients, at least over the short-term, specific follow-up is probably unnecessary. Nevertheless, a rational program of monitoring the associated precancerous conditions is in order.

Abstract
A study of potentially benign or malignant ulcer in the stomach was made to assess its role in the differential diagnosis between these two conditions. In the 201 patients observed, no statistically significant differences in frequency in the various sites were noted as regard either benign or malignant lesions. The site of the ulcer cannot be taken as indicative of its nature.
